Hello,

I am using trial license for 30 days. How do I make custom to email header? In /etc/postfix/main.cf I saw there is 2 lines:

mydomain = domain.tld
myhostname = mx1.domain.tld

I tried edit it, but still back to original. I tried to change /etc/proxmox/system.cfg 2 lines:

domain=domain.tld
hostname=mx1

but still back to original.

Another header email I need to change is X-Proxmox-CTCH-Refid: str=0001.0A150202.54A65861.005F,ss=1,re=0.000,recu=0.000,reip=0.000,cl=1,cld=1,fgs=0

My purposes are:

- White labeling for reselling
- I want custom filtering into postfix/spamassassin (adding rbl, adding filtering, etc)

Thank you
